Meiairmã
Meiairmã is a Portuguese term that translates to "half-sister" in English. It refers to a female individual who shares one parent with another person but not both. This means they have either the same mother and different fathers, or the same father and different mothers. The term is used in a similar social and familial context as "half-sister" in English-speaking cultures, denoting a sibling relationship where the genetic connection is partial. Meiairmãs are considered part of the same family unit, though the specific dynamics and closeness of the relationship can vary greatly depending on individual circumstances and family structures. The concept of meiairmã is recognized in legal systems and social customs in Portuguese-speaking countries. It is a straightforward descriptor of a specific familial bond based on shared parentage.
